TUNING PEG FOR VIOLINS AND THE LIKE.

Application filed April 18, 1925. Serial No. 24,131.

T 0 till whom it may concern:

Be it known that I, Airnnnw Hanson, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain'new and useful Improvementsin TuningPegs for Violins and the like, of which the following is aspecification.

The present invention relates to tuning devices for violins and the likeand has for its principal object to provide a peg which may besubstituted for the ordinary friction tuning pegs of a violin in the pegbox of the neck thereof. I

Another important object of the invention is to provide a peg structurehaving means therein whereby the strings of the violin or likeinstrument may be given the desired tension without the nuisance of thepeg slipping, thus requiring less tuning on the part of the player, andallowing the violin to remain in tune for a longer length of time.

Another important object of the invention is to providea tuning peg ofthis nature which is exceedingly simple in its construction, efficientand reliable, strong and durable, and one which is easy to manipulate,not likely to become easily out of order, and otherwise well adapted tothe purpose for which it is designed.

lVith the above and numerous other objects in view as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing Figure 1 is a longitudinal section through one of thetuning pegs embodying the fea tures of my invention,

Figure 2 is an elevation of one of the tuns P Figure 3 is an enlargedtransverse section therethrough taken substantially on the line;

3-3 of Figure 1, and

Figure 4 is a detail perspective view of the nut forming a part of thepeg.

Referringto the drawing in detail, it will be seen that' 5 designatesthe peg box of a violin neck having the usual peg holes 6 therein. Myimproved peg is indicated generally by the numeral 7. A'casing sleeve 8has a reduced cone shaped sleeve 9 at one end thereof. The axis of thecone sleeve 9 is out of alignment with the axis of the cars ing sleeve8. An opening 10 is provided in the wedge or cone sleeve l9 forregistering with'the usual slot 11 provided in the peg box so that thestrings may be inserted therethrough. A knob 12 or the like is recessedas at 18 for receiving the otherend of the sleeve 8, and is providedwith an axially extending threaded shank 14:. A nut 15iis adapted toreceive the threaded shank 14 and is movable in the casing sleeve 8.This nut isprovided with peripheral notches 16 for receiving beads orribs 17 provided interiorly of the sleeve 8, thereby prevent ingk'therotation of the nut. A rod 18 extends from the nut, and the end thereofhas an eye 19. After the peg has been assembled, it is engaged with thepeg box by inserting the wedge or cone-sleeve 9 into the hole 6. The endof the violin string may then be threaded through the eye 19 and tied inthe usual manner. By rotation of the knob 12, referring particularly toFigure 1, it will be seen that the nut may be drawn to the left of thefigure, thereby tensioning the springs tied to the rod 18.

A spring 20 is attached to of the knob 12, and an indicator 21 isprovided on the end thereof, and is slidable through an opening 22 inthe knob 12. It will thus be seen that as the nut 15 approaches the knob12 it will engage with the spring and force the indicator out throughthe opening 22 so that the operator will know when the nut has reachedthe limit of its movement so as to prevent the stripping of the threadsin the nut, or on the shank 14. I

This improved peg eliminatesl the nuisance of the ordinary slippingwhich occurs with the usual friction pegs. The improved peg may bemanufactured very cheaply, and can be easily and readily substituted forthe ordinary frictionlpeg. The present embodiment of the invention, ofcourse, has been disclosed merely by way of example and contains all ofthe features of advantage enumerated as desirable in the statementof theinvention. It is apparent that numerous changes in the details ofconstruction, in the materials, in the sizes, and in the com.- binationand arrangement of parts may be resorted to without departing from thespirit or scope of the invention as hereinafter claimed or sacrificingany of its advantages.

Havingthus described the invention, what the inner side I claim as newand desire to secure by Letters Patent is 1. A tuning peg of the classdescribed including a casing, a nut movable longitudinally of thecasing, means for preventing rotation of the nut, a knob rotatable onthe casing, a threaded shank extending from the knob and engaged withthe nut for sliding thereof, a spring on the inner side of the knob, apin on the spring extending through an Opening in the knob so that whenthe nut engages with the spring, the pin will. be extended through theopening, and a string engagin member provided 011 the nut.

2. A tuning peg of the class described including a casing, a nut movablelongitudinally of the casing, means for preventing rotation of the nut,a rotatable knob mounted on the casing, a threaded shank extending fromthe knob and engaged with the nut for sliding thereof, a spring on theinner end of the knob, a pin on the spring extending through an openingin the knob so that when the nut engages the spring the pin will beextended through the opening, a Wedge out of alinenient with the axis ofthe casing,

.a knob rotatable on the other end of thgcasing, a threaded shankextending from the knob into the casing, a nut threaded on the shank,means associated with the nut and the casing for preventing rotation ofthe nut in respect to the casing, a rod extending from the nut throughthe sleeve, said sleeve provided with a transverse opening in order thata violin string may be engaged with the end of the rod whereby theturning of the knob may be used for moving the rod so as to tension theviolin string attached thereto.

In testimony whereof I aflix my signature.

ANDREW HANSON.
